Orcas recorded for first time killing and eating world's largest animal, the blue whale
National Post: 'Three attacks since 2019 were recorded off the coast of Australia, in Bremer Bay, and were outlined in a report in Marine Mammal Science. The attacks were observed from commercial whale-watching vessels.
'About a dozen orcas were witnessed attacking a blue whale, estimated to be 18 to 22 metres long, on the morning of March 21, 2019. Chunks of blubber and skin, as well as most of its dorsal fin, had been bitten off, leaving “underlying bone exposed.”'
